# pacman -S msmtp
The following is an example of a msmtp configuration file for several accounts. If msmtp throws errors when using this file, search for double byte '\xc2\xa0' characters that may have been erroneously inserted. Template:File
msmtp will refuse to start if user configuration file is readable and writeable to anyone else but the owner:
$ chmod 600 ~/.msmtprc
This does not apply to system configuration file in /usr directory.
Save (with the addresses you want to use)
To: <username>@domain.com From: email@example.com Subject: A test Yadda, yadda, yadda.
as, say, "test.mail".
$ cat test.mail | msmtp -a default <username>@domain.com
Do not merely use "echo 'Yadda, yadda, yadda.'" instead of "cat test.mail". This causes at least Gmail and Yahoo to deliver the mail incorrectly.
Practical password management
The Template:Codeline directive may be omitted. In that case, if the account in question has Template:Codeline set to a legitimate value other than Template:Codeline, invoking msmtp from an interactive shell will ask for the password before sending mail. msmtp will not prompt if it has been called by another type of application, such as Mutt.
Using msmtp offline
Although msmtp is great, it requires that you be online to use it. This isn't ideal for people on laptops with intermittent connections to the Internet or dialup users. Several scripts have been written to remedy this fact, collectively called msmtpqueue.
The scripts can be downloaded from SourceForge, the most recent of which is msmtpqueue-0.5.tar.gz.
Once the scripts have been downloaded extract them using:
$ tar xf msmtpqueue-0.5.tar.gz
After that, copy the scripts to a convenient location on your computer (Template:Filename is a good choice):
$ cp msmtpqueue-0.5/*.sh /usr/local/bin/
Finally, change your MUA to use msmtp-enqueue.sh instead of msmtp when sending e-mail. Queued messages will be stored in Template:Filename.
When you want to send any mail that you've created and queued up run:
Adding Template:Filename to your PATH can save you some keystrokes if you're doing it manually. The README file that comes with the scripts has some handy information, reading it is recommended.

Send mail with PHP using msmtp
Look for sendmail_path option in your Template:Filename and edit like this:
sendmail_path = "/usr/bin/msmtp -C /path/to/your/config -t"
NOTE: Be sure that the php user have permissions to read the file or use the sytem wide config file! (Template:Filename)
To test it place this file in your php enabled server or using php-cli.
<?php mail("firstname.lastname@example.org", "Test email from PHP", "msmtp as sendmail for PHP"); ?>
Issues with TLS
If you see the following message:
msmtp: TLS certificate verification failed: the certificate hasn't got a known issuer
it probably means your tls_trust_file is not right.
Just follow the fine manual. It explains you how to find out the server certificate issuer of a given smtp server. Then you can explore the Template:Filename directory to find out if by any chance, the certificate you need is there. If not, you will have to get the certificate on your own.
If you are trying to send mail through GMail and are receiving this error, have a look at this thread or just use the second GMail example above.
If you are completely desperate, but are 100% sure you are communicating with the right server, you can always temporarily disable the cert check:
$ msmtp --tls-certcheck off
